BRIEF OVERVIEW
CNPGB(PTCOLD) and APA ROLES
PORTUGUESE NACIONAL COMMITTEE ON LARGE DAMS
CNPGB/PTCOLD is the Commission that is in charge of the Portuguese representation at the
International Commission on Large Dams (ICOLD)
The permanent representation of Portugal in ICOLD dates to 1948. The National Portuguese
Committee (CNPGB) was created by a Decree of March 21, 1952
� The CNPGB is chaired by the President of the PORTUGUESE
ENVIRONMENT AGENCY (APA)
� Its members are appointed by order of the Minister of Environment,
acting on a proposal from the Committee, which proposes individuals
with a relevant activity in the field of large dams
PTCOLD SITE http://cnpgb.apambiente.pt/
The Portuguese Committee on large Dams hosts the Website of the ICOLD EUROPEAN CLUB, and has been doing it since
2004, when its proposal and development of the site occurred.
The aim of this Website, from the very beginning, independently of its simple layout, is to help improve the role of the
Club, particularly by displaying:
• objectives;• activities from the Working Groups;• Club Symposia and its contents;• European safety legislation;• texts or reports, discussion material, position papers, other activities, etc.• links to other projects;• other proposals from the Club members.
All of the Presidencies of the Club have helped improve the contents of the site.
At the former Presidency, in 2016, EUROPEAN ICOLD CLUB MANIFESTO ON DAMS AND RESERVOIRS was launched and is
now displayed at the front page of the website.
The new President, Jean Jacques Fry, started activity in 2017 and has already introduced new ideas, such as the “Letters
from the Presidency”, “Eucold News” and the “share space” for working groups.
ICOLD EUROPEAN CLUB SITE
The EUROPEAN CLUB site is easily accessed through the main ICOLD site, within the “REGIONAL CLUBS” label.
